12mm Spacer Bolts on 10mm spacer?

gtabfknkdnme · 05-12-2013, 08:13 PM

Can the bolts from 12mm spacers be used with 10mm spacers or are they too long?

Anyone actually do it before?

I haven't don't... on the same note, I wouldn't try it. Even torqued down, I'm sure the extra 2mm would cause some vibration. IMO, not worth it. Do a stud conversion and run whatever spacer you want without the worries of what bolts to use.

Thanks for your response. Anyone else have experience with this?

If you run 10mm spacers, get bolts that are 10mm longer than stock. I wouldn't chance it with 12mm bolts. Or you can do a stud conversion.

haven't done this, but recently received wrong size bolts with my spacers, they were about a 1/2 in too long. Didn't notice when installing for rears until I drove around the neighborhood....a light clunking noise.
On another thread , someone mentioned that there may be less tolerance in the rears than fronts.

Yes, the bolts from the thicker spacer can be used on the thinner spacer... I've done this in several occasions, using my 15mm spacer bolts on my 12s, 12 spacer bolts on my 10s...

I think some misread your question, you're not using 12mm bolts on 10mm spacers, that would be dangerous.

that is what i want to do. use the bolts that came with my 12mm spacers on a set of 10mm spacers.

-unless you mean 12mm bolts (in length)?

I understand what you want to do and yes I've done it and it'll work just fine...

on a side note, I doubt the bolts that came with the 12mm spacers are actually 12mm long.

If you are doing this in the front don't even sweat it there's a lot more wiggle room. In the rear there is less, but 2mm is a very small difference so it probably would be okay.

I have a 2010 e90 and recently purchased 12mm and 15mm spacers off eBay. However, the bolts that shipped with the spacers have the same length and are extremely too long. When I tried to install the rear 15mm spacer and the wheel, one out of 5 bolts will not lock in all the way.
I ended up measuring the original lug + 15mm and cut the extra. Bolt should at least take no more than 8 complete turns.

I got too tired cutting bolts using a hack saw. I installed the long bolts along with 12mm spacers in the front with no issues. Driving on a freeway speed with no vibration.

All you do is install the spacers + wheels. Gently spin the wheel and see if the bolts will hit something.
